The present invention relates to improvements'in connecters for electric conducting wires, and the primary object of the invention is to provide an improved device of this character whereby electrical connections may be made to main line wires without the necessity ozt soldering.

A further object of ,the invention is to provide an improved conductor whereby a branch wire or conductor can be eii'ectively connected at a right angle to the main line' plan view partly cut away and in section,

and showing the form of the invention for connecting a branch line at a right angle to the main line conductor.

erring to the drawing in detail, and wherein lsimilar reference characters desig# nate corresponding parts throughout the several views, the letter A may enerally designate the form of connecter forconnect-l ing a branch line at right angles to the main line, and the letter Bpthe form of connecter employed for connecting a branch line in `parallel relation to `afmain line wire. The

.The `the-opposite end of the Applicationled October 28, 1925.v Serial No. 65,414.

vletter C may designate the main line wire throughout the several vlews, while the letter D designates a. branch line connected to the main line wire C as by the improved connecter A.

The improved connecter A which is preferably Aformed of one piece of brass or copper, is shaped into a rectangular hollow body being open at each end, and embodying a top. wall 10, parallel side walls 11, and a bottom wall 12. Extending longitudinally from one end ot the body oi the connecter,fand formed in the side walls 11 thereof, are transversely aligned slots 13 having their lower edges disposed `flush with the inner face of the bottom wall'12 and as is 'clearly illustrated in Figure 3. At a; point midway of the body of the connecter, a portion of the top wall 10 is pressed downward/ly into contacting relation with the inner face of thebottom wall 12 for providing a, transversely extending stop 14 which is intended for limiting the distance which the branch lconductor D may be inserted into the connecter body.

Set screws 15 embodying threaded shank portions 16 extending in screw threaded relation through the top wall 10 et the connecter body, have substantially flat heads 17 formed at their inner ends. These set screws 15 which are disposedto each side of the stop 14, are adapted to be turned intov the body of the connecter for firmly pressing the conductor wires C and D into tight trictional engagement with the inner face of the bottom wall 12. The set screw 15 which is distit) posed at the main line connection end ofthe f cnnecter, has its axial center disposed outwardly of the inner ends of the slots 13 as illustratedI in Figure 2.

In use with the form for connecting a branch lincat a right angle to the v.main line, the connecter is first positioned with the main line wire C extending through the slots 13, and after which the set screw may be bturned for firmly-clamping the line wire againstthe inner'fac'e of the bottom wall 12. branch wire D may then be-inserted into connecter into eugagement with the stop 14, and after which the second set vscrew may be turned into the connecter for firmly clamping the branch line against the inner face of the bottom wall 12.

With Figures 5, 6 and the form of invention as shown. in

7, and-which type 1s particularlyl well adapted for connecting. a..v

branch line in parallel relation to the main line, one of the side walls 11 is provided intcrmediate its upper and lower ends with a longitudinally extending slot 18 which opens at. both ends ot the body of the connecter'. llt will bc apparent that this slot 18 permits of the connecter being slid over the main line wire longitudinally thereof. After the connecter has been thus positioned over the main line wire, a branch line wire may be inserted into one end of the connecter body and be clamped against the inner face ot the bottom wall as by the set screw 15. lBy so forming the slot 18 intermediate the upper and lower edges of the side walls, forms a flange at one side of the bottom wall for preventing accidental displacement ot the Wires.

lt will be observed in both forms oir the invention, that no distortion of the main line wire is caused by attachment of the connecter thereto, since in both forms,y the main line wire is clamped between :dat surfaces formed by the head 17 of the set screws, and the flat t inner space of the bottom walls ot the vconnecters. I

Various minor changes may be made to the speciic forms of the invention herein shown and described, without departing` from the spirit of the invention or the scope of the following claims.

l claim:

1. ln a connecter for electric wires, an elongated hollow connecter body open at each end and having transversely aligned slots )pening at one end of the body, means carried by the body between the slots for clamping a wire in said slots', and means :tor clamping a branch wire in the Opposite end of the connecter body.

2. A connecter for main and branch line wires comprising an elongated hollow con 'necter body of substantially rectangular shape 4in cross section, forming a top wall, side walls, and a bottom wall, said side walls being provided with aligned slots" opening at one endk ot the connecter body, clamping means threaded yinto the' top wall of the body above said slots for clamping engagement with a main line wire, and a second clamping member threaded into the top wall of the body adjacent the opposite end tliereof and adapted for movement toward the bottom wall of the body into clamping' engagement with a branch line wire.

3. A connecter for main and branch line wires comprising a hollow connecter body open at each end and including a top wall, side walls, and a bottom wall, said side walls being provided with aligned slots opening at one end of the connecter body and having their lower edges-lying in a like plane with the inner face of said bottom wall, means threaded in the upper wall of the connecter body intermediate the ends of said slots for movement toward and away from the underlying bottom wall, and means for securing one terminal of a conductor within the opposite end of the connecter body from that in whichsaid slots are formed.

4. A connecter for connecting a branch line wire at a right angle to a main line wire comprising a hollow connecter body open atV each end and including a top wall, side walls,4 and a bottom wall, transversely aligned slots .provided in the side walls and opening at one end of the connecter body tor the reception of the main line wire transversely ofthe connecterv body, means :tor clamping the main line wire within said slots, a stop formed substantially midway of the connecter body and closing the opening through said body, said stop serving to limit the insertion oit a branch line wire into the opposite end of the connecter body, and means for clamping one terminal of the' branch line wire in longitudinal relation within the connecter body. i

5. ln a connecter for main and branch line wires, a hollow connecter body having a longitudinally extending opening in one side wall thereof for thefreception of a main line wire, and a screw carried by the top wall of the connecter body and movable toward the bottom wall of the body for clamping the main and branch line wires thereto.
